Thanks for your reply Martin. I have version 5. After reading your notes I believe I put in 10.5 hours for time zone and then clicked yes for daylight saving which I assume would have adjusted the zone to 11.5 hours putting me an hour out. I will put in 9.5 hours and then click yes for daylight saving. Hopefully that will see me right.
Thanks for your very useful setup notes Martin. your help much appreciated, Now just need another clear night which may not be for a while.
Cheers, Richard
